Patented June 27, 1933 UNITED STATES PATENT OFFICE WARD LEATHERS, OFHAWORIH, NEW JERSEY, ASSIGNOR TO THE QUADREX. CORPORATION, A CORPORATIONOF CONNECTICUT HAND VACUUM CLEANER Application filed August 21, 1930.Serial No. 476,834.

The object of my invention is to produce a more practical and efficienthand-vacuumcleaner than heretofore made.

This apparatus is radically different in 5 many respects. It has as itsfirst object the making of a cleaner that may be handled more like abrush and dust-cloth combined.

The first consideration in its general development was to so locate theweights, back of 1 the griphold, and underneath the hand so that thenozzle extension may be swept around freely with the wrist motionrotating said extension freely, approximately about the center ofkinetic rotation of the entire machine. Heretofore hand cleaners havebeen made with the motor-blower unit in front of the handle where theyfurnish a clumsy weight-mass and annoy a dexterous person.

I have set forth in the following specifications a complete descriptionof my invention, and to the same have appended drawing of which- Figure1 is a side elevation Figure 2 is a transverse cross-section ofbrush-nozzle Figure 3 is a partial longitudinal crosssection of the sameFigure 4 is a partial cross-section of motorblower assembly Figure 5 isa plan view of the under side of the suction housing.

Figure 1 shows my hand-vacuum-cleaner approximately half size. Here, 1is a hollow air-duct-handle, preferably of hard fibre tubing. The lengthmay be as desired. It supports on the forward end, rigidly attached toit, a hollow nozzle attachment 2. It supports on its rearward end insimilar manner a motor-suction air-filter assembly 3. To the forward endof 2 is rotatably attached a suction-nozzle assembly 4:. The unitassembly 3 has within the filter 6 the motor-suction unit. At 7 there isan electric switch, at 8 a flexibly joined electrical connection. Thefilter-bag 6 made of suitable fabric, is joined in any suitable mannerto a supporting ring 9 provided with a handle 10, whereby the filter 6may be joined to the assembly 3 by means of suitable latches such as thebayonet joints shown at 11.

Figures 2 and 3 show cross-sections of the lower part of thesuction-nozzle assembly, approximately actual size. A brush 12 providedwith the usual back is encased in a clip 13 made of sheet metal or othersuitable material such as stiil' sheet rubber attached thereto suitablyas by rivets. The nozzle casing 14 is preferably of stamp sheet metal,

although it may be cast if desired. 15 is a rubber-bumper andnozzle-nose, attached in any desired manner, as shown, consisting of arubber-band held on by tension and rubber cement. The brush 12 isdropped in at the of the nozzle and held rotatively in place by pins,plugs or screws, or other suitable means, shown at v16.

In operation the side movement of the brush, due to its hingedcharacter, permits it to automatically open the port on its forward sideand close the port on its rearward side, which action is reversible inuse.

Figure 4 shows a partial cross-section of the motor-suction assembly 3.A member 17, which it seems desirable to make in the form of a casting,provides the attachment for the handle 1, the air inlet to the center ofthe rotor, the top and side casing for the rotor, and an outside rim 18to which the ring 9 is joined as above described. In the manufacture ofthis device this is the only part that need be made of cast material,the remaining parts, being preferably stamped. A motor-housing 19 issuitably joined to a supporting member or plate 20. At 21 I haveprovided a rubberbumper attached in any desired manner, which will helpto protect the fabric of the cover 6 when the machine is not in use.

Figure 5 is a view of the part 17 from the underside wherein 22 is theinlet-opening to the suction. 23 is the suction-chamber. Outlet ports24, to any desired number, permit the exhaust to egress freely to thefilterchamber 25.

Having set forth my invention in simple, understandable terms, so thatall familiar with these arts may understand, I wish it understood thatthe principles involved in my invention may be applied by a multitude afilter attached to the periphery of said plate" and enclosing the portedannu ar flange and the motor-suction-unit; a rigid tubular handleattached to the plate with its bore in communication with a hole throughthe plate into the fan chamber; and a suction nozzle on the outer end ofsaid tubular handle.
